LOCOMOTIVE HEAD-LIGHT.

SPECIFICATION forming part of Letters Patent No. 234,410, dated November16, 1880.

' Application filed March 24,1880. (No model.)

To all whom it may concern Be it known that 1, WILLIAM KELLEY, of thecity of Baltimore and State of Maryland, have invented a new and usefulImprovement in Signals for Locomotive Head-Lights; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof, which will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon.

'My invention relates to a signal which may be exhibited, as desired, infront of the lantern to indicate that the train is immediately followedby another, or as a danger-signal, or for other purposes.

This invention is designed for the use of railroad companies, and isintended to effect a saving to said companies by dispensing with lampsof different kinds and the oil necessary to supply them; and theinvention consists, first, in combining with the head-light lantern, atthe front parts thereof, on either side of the rim, a small box havingfront and side panes of glass, which will give front and side lightsfrom the lamp placed within the lantern.

The invention consists, secondly, in providing an opaque-leaved coverfor the front and side parts of the said boxes and in the mechanismwhereby the said cover is manipulated from the cab, or otherwise, as maybe desired.

In the accompanying drawings, Figure l is a perspective view of theinvention. Fig. 2 is a rear view. Figs. 3 and 4 show details of theinvention. Fig 5. is a view in horizontal transverse section, showingthe means by which the light from the lantern is reflected through thefront and side panes of the side boxes.

Similar letters of reference indicate similar parts in all the views.

A is the head-light lantern, of which a is the front rim. The lamp isplaced within the lantern in the ordinary manner, the lantern beingprovided with the usual reflector A, Fig. 5.

B B represent the boxes placed at the front of the lantern, which boxeshave openings at their fronts and outer sides covered with white glass.Colored panes of glass are placed over the white panes of glass, and maybe either stationary or removable, being made to slide either endwise orsidewise, as may be desired. It is to be understood that those portionsof the face of the main lantern behind the boxes are removed, so thatthe light from the lamp on the inside of the main lantern will be seenthrough the fronts and sides of the boxes.

To the sides of the main lantern are hinged opaque-leaved covers (I, towhich are attached rods D, which run back toward the cab.

When it is desired to expose the front and side lights of the boxes theleaved covers are drawn back from the position shown in Fig. 1, so as tocause them to lie flat against the sides of the main lantern. This maybe done by means of the rods D, or, if the rods are not used, it may bedone by simply moving the leaved covers by hand. Under the boxes may beplaced catches a, and similar catches may be placed at the sides of themain lantern for holding the leaved covers in their closed and openedpositions. tion is shown in Figs. 3 and 4.

Behind the main lantern may be placed pockets cl, for holding thecolored panes when made removable. Glasses of various colors may beprovided, such as red, green, or other colors in use on railroads assignals for different purposes.

By means of this invention brilliant side and front colored lights areobtained in a simple manner, and the necessity of using a large numberof lanterns of different descriptions is avoided.

The invention may be applied to any lantern now in use.

I am aware that it is not new to attach bulls= eye lenses to the upperfront portions of the face of a headlight lantern, which show frontlights from the flame within the lantern.

I am further aware that signal head-lights have been used heretoforehaving a chamber outside of each side thereof, which chambers have frontand side panes of glass, through which the light from the main lanternis reflected but such a construction requires the aid of a mirror orreflector within each of said chambers in order to direct the rays oflight.

In my patent N 0. 209,405, dated October 29, 1878, are shown framesattached to the sides of the front rim for showing side lights, thefront and side lights being transmitted through Thisconstruccolored-glass panes hinged or leaved together in a frame,somewhat similar in construction to the opaque-leaved covers employed byme for concealing the front and side lights in my presentinvention. Suchprevious invention, therefore, I do not claim herein but,

Having described my invention, I claim- 1. In combination with alantern, A, having portions of its front face removed, the boxes, B,attached to said face at either side of the rim in front of saidopenings, and provided with front and side glass panes, substantially asdescribed, whereby the light within the lantern is seen through thepanes of the boxes, as set forth.

2. In combination with the lantern A and boxes B, affixed to the facethereof, the opaqueleaved covers 0, hinged to the lantern, substantiallyas specified.

3. In combination with the lantern A, boxes B, and opaqne-leaved covers0, hinged to the lantern, the rod D, leading toward the cab formanipulating the hinged and leaved covers, substantially as specified.

In testimony whereof I have hereunto subscribed my name this 21th day ofMarch, 1880.

WILLIAM KELLEY.
